Teflon is a better dielectric, but we are talking about a 60hz sine wave, not a 20-20,000hz complex signal.

Yes, this is why I ask ... AC is only 50hz or 60hz and Teflon is not flexible enough...
Hmmm......guess manufacturers using teflon insulation for speaker cables n IC 's haven't got the message.
The conversation was about power cords.
Dave
If a speaker cable shorts you might blow your amp and if an IC shorts you will get a loud hum but neither will blow a circuit breaker, possibly cause a fire or electrocute someone. Also I have never seen an IC or speaker cord that is UL approved. Remember that I said I made and use Teflon power cords (at my own risk) along with IC's and speaker cables but don't believe any could pass UL inspection for the reasons stated above which was the original topic of the post.
my reply to your earlier post.
Sheesh !!!
Run a PLC? Where does the noise come from ? If the noise on the line is corrupted. , it makes things harder for certain filtersYMMV n FWIW
